Abstract: ABSTRACT OF THE DISCLOSURE          A scroll-type refrigerant compressor unit is assembled by inserting parts into a compressor housing in the predetermined order and by finally securing a front end plate onto the compressor housing by bolts, whereby the production of the compressor unit is simplified.          A drive shaft is supported by a single radial bearing, and a disk rotor having a drive pin to effect the orbital motion of the orbiting scroll member is fixedly mounted on the inner end of the drive shaft and is supported on the front end plate by a thrust bearing.  Thus, the drive shaft and, therefore, the compressor unit are made in a reduced length and the deflection and vibration of the drive shaft are securely prevented.  A lubricating system is provided to lubricate shaft seal assembly on the drive shaft wherein the oil in the compressor housing is directed to the shaft seal cavity and returns to the interior of the compressor housing after lubricat-ing the radial and thrust bearings and other parts.          A mechanism for automatically reducing the compressed fluid amount at an increased high speed operation of the compressor unit is proposed.

Abstract: Abstract A method for forming feedthrough connections, or via studs, between levels of metallization which are typically formed atop semiconductor substrates.  A conductive pattern is formed which includes the first level metallurgy, an etch barrier and the feedthrough metallurgy in the desired first level metallurgical configuration.  She via stud metal-lurgy alone is then patterned, preferably by reac-tive ion etching, using the etch barrier to prevent etching of the first level metallurgy.  An insulator is then deposited around the via studs to form a planar layer of studs and insulator, after which a second level of metallization may be deposited.

Abstract: ABSTRACT OF THE DISCLOSURE           A poppet located in the opening of an annular seat member for use in a body for forming a check valve. The poppet has a resilient seal for engaging a seat formed in the seat member for forming a seal therebetween and which also prevents removal of the poppet from the opening of the seat member.  A spring normally urges the poppet in a direction to urge the seal against the seat.  The poppet has ribs slidably located in slots formed in the seat member to prevent rotation of the poppet to minimize spring failure. The poppet and seat assembly can be located in the body in either direction to allow the check valve to be used for different purposes.  Safety stops are provided in the body for the poppet to prevent shearing of the seal in the event of use in excessive pressure conditions.

Abstract: ABSTRACT OF THE DISCLOSURE          A transmission collision avoidance scheme for a distributed network data processing communication system including a half-duplex communication board coupled to the system bus.  In addition to a serial data bus and a clock bus, the system bus is configured to include a busy status line that is monitored by each device connected in the system.  When a device desires to send a message, it initially proceeds to busy out the busy status line, by causing a busy flag to be placed on the line.  It also checks the busy status line in order to ascertain whether a busy flag was already set, namely, whether another device has already requested service.  If the bus is busy, the device cannot transmit until the bus becomes free and the requesting device resets the bus busy flag for a retry interval.          Assuming that the bus is free, the transmitting device proceeds to transmit.  When the device for whom the message is intended receives the message, it sends an acknowledgement message back to the transmitting device, signifying a successful transmission.          Because of circuit operation and propagation delays, there exists the possibility of more than one device setting a busy flag and checking the status of the bus without being aware that another device is simultaneously requesting use of the bus.          In this event, a transmission collision will occur, so that the intended receivers see no sensible transmission and, consequently, return no acknowledgement messages to the collision-participating transmitters. When a transmitter fails to receive an acknowledgement message, it assumes that a collision has occurred, and proceeds to repeat the above procedure for transmitting its message pursuant to a prescribed priority scheme, the higher priority device being assured of transmitting its message without a collision on the bus with a message from the lower priority device.
